    Silicone is fairly flame-retardant. A properly molded and sized silicone exit orifice would produce a continuous fart noise the entire time this device goes off. This is a bad idea and you should do it. I expect it to not improve performance of the device in any way.

    Not sure if this was discussed before but i would suggest mixing baking soda directly into the pyrotechnic mixture. What this will do is slow down the reaction speed and potentially reduce fire hazard.
    Depending on the mix it may also help produce more smoke because the added CO2 will reduce the flame

      Those smoke grenades definitely need some baking soda mixed in with the mixture. It will also stop the flames. Also, the top of the smoke grenade flying off could cause issues. No one wants a piece of the smoke grenade flying at them. I suggest a small empty space with a screen and holes drilled in the top or bottom. The holes should let the gasses excape, while keeping the smoke grenade whole.

    Those look better than any of the homemade smoke grenades I've seen online, and comparable to the Army issued ones I used to use. An obvious difference is that the military smoke grenades have a tape covered hole in the bottom that the smoke comes out of, and they don't pop the fuse out during use. Perhaps instead of putting plaster in them, you could put a ½-¾" hole in the center of the bottom and try to secure the caps better, perhaps with Loctite or an adhesive that weakens once it gets really hot, so that it won't pop off right away, but will be removable after use.

    Copper is very malleable. Plumbers have tools for "flaring" copper tubing to expand one end of the tube. Suggest that you flare the end of the copper tube so that it bends and seals in the top to also stop chunks from being ejected. You can use some other sealant to hold it together or a crude metal snap ring that holds the flared copper tube in place.

    You could use a big washer just big enough to fit your canister hole size, but with a center hole small enough to prevent your perforated tube from coming out. Then go to the hardware store and get a snap ring that just bigger than the washer (they will have them at parts stores and hardware stores) the snap ring should prevent the washer from being able to come out because of the tapered neck/and or the threads of the neck. You could also drill smaller holes through the washer so it helps prevent it from acting like a rocket.

    You are essentially making slow-burning solid fuel rockets, but without compression. If you restrict the nozzle more you will either create a rocket and see it flying or a bomb.
    Taking that into account, I'd apply some lessons I learned from making rockets.
    * add a liner to the can before filling it, something like fireplace sealant. Just brushing it in 2 coats should be enough, or you could fill and pour it out. It prevents heat from passing through the metal can and lighting shit on fire, it also protects the metal against most of the heat.
    * make your fuel pourable, when you pack it like that it's probably filled with air bubbles in between chunks that heat up and explode, causing the chunks to fly out. Pouring it means smaller air bubbles and you can vibrate to get rid of most of them. Also allows better control of how much fuel you are adding exactly.
    * Increase the center hole chimney by 50% and use a proper steel pipe, not just a broom handle, this will make things safer and lower pressure, at the cost of only a little less fuel. almost half your fuel in weight is the outer 10% of the content of the can.
    * You could probably benefit from adding some kind of liner between the fuel and the pipe. Fireplace sealant works, but you don't want the liner to block the holes, so probably paint the pipe with the liner before you assemble everything.
    * only perforate the bottom half of the chimney pipe, you don't want the top to burn, you want it to burn bottom up. Holes in the middle and top are igniting your fuel all around, you can see this in the video, this creates a short, hot and messy burn. Probably burning some of your smoke into carbon before it leaves the can.
    * make an actual cap of burn-safe material, like fireplace sealant with rockwool that both keeps the metal tube in place once hardened, and prevents the fuel from combusting from the top. Make sure you dont block the tube with this.

  • @HistoricalFidelity
    @HistoricalFidelity 4 месяца назад +10

    Hi, I have a couple ideas that I believe are worth investigating. First, try using the finely perforated center tubes found in automotive oil filters. The fine perforations should decrease the “chunk” events to minimal levels and may even offer protection from the fuel surrounding the tube from ignition by the primer thus allowing a more optimal bottom to top fuel burn. The finely perforated tube could also theoretically control the rate of smoke released due to higher resistance for fluids to flow through 100+ small orifices vs 10-15 open circles, which should help keep more heat within the system, which could culminate in greater burn efficiency resulting in either elongated burn times or producing more smoke overall. I would suggest a large capacity oil filter for a diesel truck as they would have the longest tubes for you to use.
    Second, solid fuel rockets often mold the fuel with a star pattern center channel to increase fuel surface area and to promote a more equal burn rate. If I remember correctly, the star pattern also helps protect the fuel column from pre-igniting before its proper time in the ideal bottom to top fuel burn.
    I honestly wish I could test these ideas myself but would be very intrigued to hear your findings if you include these in your next smoke canister video. Thanks for considering!

    • @HistoricalFidelity
      @HistoricalFidelity 4 месяца назад +1

    Our devices had portholes drilled in the shoulder or neck of the cannister and the holes (4) cover with a durable tape. It featured the same tube in the center. The cannister had a thicker neck with finer thread to prevent the striker from being ejected allowing the portholes to do the work. A balance between pressure and hole size and number of holes need to be tested to prevent it over pressure and popping it very loudly. Pressure also changes the volume, particle size and (hang time). A lot to test and many variables. Enjoy and good luck.

    If you want to reduce the outside temperature of the canister, why not coat the inside with the same plaster you used on the top? It would detract from the total volume of compound that you can place inside, but depending on the thickness of the plaster layer, it could be reduced from red hot to warm or even cool to the touch while active.
    Side note:
    The plaster you used is a powder, but you may be able to find one that can be made into a liquid, which would make for a much simpler coating process.
    1. Mix plaster.
    2. Pour a small amount into the canister.
    3. Cover.
    4. Roll until thoroughly coated.
    5. Cure.
    6. Repeat until desired thickness is achieved.

    Try packing the mixture into the can with a fixture like they use to make rockets or strobes. This should remove the need to put the bicarbonate in to take up dead space. Place the perforated tube inside the can and then use a tightish fitting dowel to occlude the inside of the tube. Remove the dowel after the can is tightly packed. If you’re having trouble with the mixture compacting, you can probably use paraffin as a binder. You’ll need to melt the wax and add the mixture to it then sufficiently mix it into a paste.
    You could also use a card stock sleeve to block off the upper holes. Get the paper thickness right and it will burn away when the holes are reached.

    As another commenter pointed out, this is most likely burning similarly to a solid rocket motor i.e. vertically along the entire fuel grain. I recommend mixing for a slower burn, and increasing the burning surface area in a star shape for a higher initial surface area. It'll lead to a much more constant burn rate because as the grain burns it'll round out the star, meaning the total burning surface area remains relatively controlled.

    If you use plaster to cap it off maybe mix some rockwoll into the plaster. It is heat resistant and should help to prevent cracking. Or use only only rockwoll and put a metal screen ontop to prevent it from being ejected. It also would allow smoke to go through. And last but not least. Make 2 holes in the container (top and bottom). This way you reduce the gas velocity and backpreassure (which should help with stuff geting ejected). Some aluminium foil could be used to cover the bottom hole. It will rupture easily when the device is ignited.

If you then pack the composite around the assembly before removing the rod, the uncured composite should form itself into the holes of the tube, and when it cures it'll be fixed in place.

    how would adding an additional vent hole in the bottom (sealed with low temp wax) effect things. i imagine it would lower the thrust thats throwing the chunks out but im curious how it would effect the smoke dispersion

  • @anonpatriot5649
    @anonpatriot5649 3 месяца назад

    A few ideas to try, you can weld the 3/4" core tube to the cap, perforate only the top portion, just above the compound fill line. the fuse will ignite the compound on the top but the smoke will travel along the center core to a blow out valve at the bottom of the device. (a piece of tape on a dilled hole) you could add more compound per device this way as well. another idea is to reduce the size of the core to 1/2".

    Try wrapping the fuse in several layers of aluminum foil to keep it from igniting anything early. They do this on many fireworks.

    A rounded bottom with the weight low down could make it land "feet down" always, further reducing fire hazard. Or sticking with the cylinder shape make it imbalanced so it comes to rest at a defined point. Could angle your "exhaust pipe"upwards then.

  • @thomasg4324
    @thomasg4324 4 месяца назад +17

    *1) Although fire hazard is something to be avoided, I guess.....if someone needed to pop smoke, I do not think starting a fire inadvertantly is any concern to them.*
    2) Why not just try percentages of baking soda directly into the fuel mix, and find the sweet spot. Then more fuel mix can be added to the head of the burn chamber.
    3) Duration of smoke is rather long. Back to the idea that someone needs smoke NOW, and as much of it possible covering as wide an area as possible...wouldn't a 3/4" burn core straight through...coupled with central ignition...cause two opposing smoke plumes twice as thick and twice as fast? *Wouldn't **_that_** be preferable to someone needing to pop smoke?*
    4) Isn't it preferred to have the smoke plume ejection along the ground, rather than shooting well above line of sight? The smoke should rise anyway, so wouldn't two opposing plumes along the ground be far superior at creating a wide screening cloud? #InterestingVideos

      Long duration steady release of smoke is the basic idea. Two outlets, half the duration. Not necessarily a bad thing but a tradeoff. It's probably harder to fabricate a double-ended device, and would be tricky to make it blow caps off both ends.

Love the progress you're making though. I was also wondering if chucks would blow if you were able to have some sort of chicken wire wrap inside.....

    Change the core to a stainless mesh that you have rolled. Roll a few wraps. When you get to the top flare the layers out so that they sit under amd flare out beyond the opening orifice. Pick a fine enough mesh that won't create to much pressure but will stop all flaming particles from leaving. Should hold up plenty as it will take the heat. Same idea as a flame arrestor on a muffler

    On one of the cans in the last experiment it looked like the bottom of it was visibly heating up. I think the 3/4 in tube that runs the whole length of the can is allowing the bottom to have a hot spot. A 3/4 in hot spot on the middle of the bottom of the can doesn't seems that dangerous compared to the sides of the can heating up for concerns of a fire hazard but I'm thinking that a small layer of sodium bicarbonate or type of buffer at the bottom before filling in the compound would possibly help with that.

    A piece of fine screen shaped somewhat like a star would be more porous to the smoke at all levels and would allow the materials burning farther towards the edges to emit their smoke more evenly. The star points should reach the edge of the can and will help even out heat conductivity, in an ideal world the base of your 'star tube' would be a bit smaller on the far end, but that's a moderately complex geometry. Mixing in a small amount of a retarding mixture like baking soda will also slow the reaction slightly. Using pre-form molds you can also make individual pucks and place filler layers between them. If you can lower the temperature enough you can switch to something like piping for a more flexible design space as well.

  • @ClashClash89
    @ClashClash89 4 месяца назад

    You could improve the plaster cap by incorporating textile strips. Like they use in plaster-bandages or just strips of burlap.
    That should add plenty of strength without adding volume.
    And you might be able to further reduce the risk of accidentally setting something on fire, by leaving the top third of your perforated tube, imperforated. That should increase the path any embers or flames or small chunks would have to travel before reaching anything combustible.
    Just be aware that you may run into pressure problems if you leave to much unperforated, considering the volatility of your mix…

    Another sub suggestion here. Make the perforations smaller at the top and larger at the bottom. 1/4" at the top 5/16" in the middle and 1/2" at the bottom. Also You might want to limit the amount of holes at the top in smaller size if you wish the bottom to burn faster. Could also just try a lot of small holes and play with the ratio of holes along the length of the cylinder until you reach desired result!
    My experience is about 15 years of construction and MacGyering with my grandfathers in my youth and now into my adulthood as a Maintenance Mechanic on automated robots haha. Hope it works if ya try it!
    Also what @Exandria said would be very good in terms of insulation if you just put starlight in a thin coat around the canister then maybe leave some of the top rim uncovered and flex seal it all except the portion which needs to blow off.
    As Smokey said, Only you can prevent forest fires!

    After seeing this, I'm curious if this monolithic design is even the best route. If you got several much smaller perforated rods and placed them throughout the compound you'd get a higher volume of compound and comparable surface area for escape. (you could even fine-tune the surface area, compound load, burn-rate, etc. fairly easily by changing the radius of the tubes, number of perforations in the tubes, positioning of the tubes, number of tubes, etc.)
    From what you say here it sounds like you were limited to a monolithic design previously because otherwise the compound would break down catastrophically during ignition, but if perforated rods can provide support while letting the smoke escape, it seems like a less-monolithic design could work better.
